The product lineup
Odyssey-2
General-purpose world model with improved physical accuracy.
Starchild-1
Real-time multimodal model generating visuals and audio simultaneously.
Agora-1
Lets multiple agents interact in a shared simulation space.
THE PROMISE
A frontier beyond text-only LLMs — applications in robotics, game generation, autonomous driving and AR/VR. Founders bring deep self-driving pedigree from Voyage, Cruise and Wayve.
THE CAVEAT
Still early: coherent generation tops out at roughly 1–2 minutes. Large-scale simulation compute cost and long-term consistency remain open challenges, with real-world benchmarks yet to come.
